[CF6-4] Metrical relationships: distance and direction

Relationships between spatial features that define their relative position. Spatial autocorrelation is a fundamental principle based on Tobler’s first law of geography, which states that locations that are closer together are more likely to have similar values than locations that are farther apart.
